The annual Live Interventional Neuroradiology & Neurosurgery Course (LINNC) is one of the most important congresses in the neurosurgery and neuroradiology field. LINNC 2009 was held on May 25th this year and lasted for 3 days. In this article, the authors introduced the main points of the congress The congress mainly discussed some hot topics at present time, including both the clinical and fundamental studies of cerebral arteriovenous malformation. Ischemic cerebral disease and intracranial aneurysm, etc. Both neurological and neuroradiological case demonstrations related to the topics, and the main course of the congress were altemately performed. Recent advances in imaging technique and clinical application, such as Dyna-CT and Xper-CT, were also presented on the congress.

Objective To observe the therapeutic effect of Ningxin Granule Heart-Quieting Granule for pediatric viral myocarditis.Methods Totally 60 cases of pediatric viral myocarditis were randomly divided into treatment group (n=30) and control group (n=30).There was no significant difference between two groups in sexuality,age and pathogenetic condition.Patients in treatment group took Ningxin Granule,while ATP,CoA,Vit C,Inosine and Ribavirin were given to control group by intravenous drip.Results The treatment group was superior to control group in relieving symptoms,reducing the bearing premature,CK-MB,cTnI and LVEDD,and increasing LVEF.Conclusion Ningxin Granule can obviously relieve symptoms and signs,reduce the bearing premature,decrease the level of myocardial enzyme and improve the cardiac function.

The study on the Rauvolfia verticillata (Lour.) Baill., which belongs to Apocynaceae, was carried out to look for its chemical constituents and pharmacological activity. The isolation and purification were performed by chromatography on silica gel, Sephadex LH-20 and ODS (octadecyl silane) open column. The structures of obtained compounds were elucidated on the basis of physicochemical properties and spectral analysis. Three indole alkaloids and one acridone alkaloid were isolated from chloroform layer extract and identified as ajmalicine B (1), sandwicine (2), raunescine (3) and 7-hydroxynoracronycine (4) separately. Ajmalicine B (1) is a new compound belonging to indole alkaloid. Compound 4 as an acridone alkaloid was a new type compound isolated from Rauvolfia genus for the first time. We also did some biological activity research on the new type compound (4) to explore other pharmacological activities in addition to antihypertensive activity.

There are many practical problems to be solved in 7-year program teaching.The whole teaching thought should be widened further.With practical experiences of diagnostics teaching for 7-year program students for many years,we have summed up the results of 7-year program teaching reform.Appling to the holistic teaching mode reform of diagnostics of 7-year program,we have attained the first step achievements.

Objective To apply the IQM quality data of the GEM 3000 blood gas analyzer to evaluate the instrument performance and to compared it with the traditional evaluation method .Methods The precision and accuracy were calculated by using the IQM data ,the external quality control substance was adopted to verify the main performance indexes of the blood gas analyzer .Results The precision of PH ,PCO2 and PO2 calculated by using the IQM data was 0 .02% ,2 .16% and 0 .63% ,which by the traditional e-valuation method was 0 .07% ,1 .68% and 1 .28% respectively ,the accuracy of PH ,PCO2 and PO2 calculated by using the IQM data was 0 .00% ,1 .15% and 0 .49% ,which by the traditional evaluation method was 0 .11% ,2 .91% and 1 .07% respectively .Conclu-sion The intelligent quality management can provide objective and reliable indicators for the performance evaluation of the blood gas analyzer ,and compared with the traditional performance evaluation scheme which is more simple and convenient to operate .

With the development of the medical imageology, the lumbar pain resulted from vertebral compression of the anterior column can be treated through percutaneous vertebroplasty (PV). PV has some advantages, such as short operative time, definite pain release, less complications and better security. However, there are some indications and contraindications in PV. PV can reach the prospective effect after handling these indications and contraindications. The authors reviewed the predominance, anatomy, indications, contraindications, assessment before the operation, operative methods, complications of PV in this article.

Objective Analysis of clinical features and treatment of nasal type NK/T cell lymphoma, to improve the understanding of this special type of lymphoma.Method The clinical data of 34 patients with nasal type NK/T cell lymphoma confirmed by pathology were retrospectively analyzed.Result In 31 cases, 26 cases were EB virus (EBV) infection positive, recent Treatment Effectiveness in the positive group was significantly lower than the negative group (38.46%vs. 87.50%;P<0.05) . Follow up showed until October 2015, 19 of 34 patients died. Among them, 17 cases died of disease relapse or progression, 2 cases died of other diseases. 15 patients survived (11 of them were disease-free) and the median overall survival time was 37 months. The 2 year overall survival was related to clinical stage, B symptoms, EBV infection (the P values were 0.017/0.001, 0.005, and 0.039 respectively).Conclusion EBV infection is associated with patient's treatment response in NK/T-Cell Lymphoma; and the prognosis is associated with clinical features such as clinical stage, B symptom, and EBV infection.
